APPARATUS FOR TREATING THE SOIL.

SPECIFICATION forming part of Letters Patent No. 768,257, dAug 23, 1904.

Application filed May 26, 1904..

T0 (LU whom, it may concern:

Be it known that I, GEORGE H. ADAMS, a citizen of the United States, residing at Phoenix, in the county of Maricopa, Arizona Territory, have invented certain new and useful Improvements in Apparatus for Treating the v Soil; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference out in the least disturbing the roots of the plants.

My invention consists, further, in the provision of rotary disks, which may be of different diameters and interchangeably held to a suitable shaft, with means for raising the shaft or applyingpressure thereto to cause the disks to cut but short distances or deep into the soil for the purpose of afiording an opportunity for the roots of plants to reach down into the soil for subsistance, moisture, &c.

The invention consists, further, in the provision of an apparatus of the character described especially adapted for use in regions where farming is done by irrigation and embodying various details of construction and combinations of parts, as will be hereinafter more fully described and then specifically defined in the appended claims.

I illustrate my invention in the accompanying drawings, in which Figure 1 is a perspective view of my im- Fig. 2 is a side elevation.

Reference now being had to the details of the drawings by letter, A designates a car- Serial No. 209,959. (No model.)

riage, having a tongue secured thereto, and fastened to the forward portion of the carriage are two stub shafts B B, on which wheels 0 C are journaled, and to the rear of the frame is a trailer-wheel, thereby making it possible to conveniently turn the carriage within a short radius. Pivotally connected with the cross-beam E of said carriage is a frame F, in the parallel side beams of which is journaledin suitable bearings a shaft Gr, upon which are mounted the disks H. These disks may be of any size and made so that they may be easily interchanged in order to provide means for cutting'at different depths in the soil. A suitable handle R is provided, which may be of any suitable shape or size, and in the present instance I have shown the handle as being made of two converging beams O 0, connected together at their rear ends witha cross-piece S. The forward ends of the beams O are fastened to the beam E of said frame and projecting rearward fulcrum over the rear beam E of the frame, affording means whereby pressure may be applied to the rear portion thereof when it is desired to have the disks cut deep into the soil.

By the provision of the apparatus described and illustrated I have found by practice that I am able to cut and pulverize the soil at va-' rious depths without disturbing the growing plants and afiording an opportunity for the roots to reach down deep in the soil to get the necessary moisture and nutrirnent so essential to their hearty growth andwhich is of vital importance in farming regions where irrigation is carried on. V v 7 While I have illustrated in the drawings a particular construction of apparatus as embodying'my'invention, it will be understood that I do not limit myself to the particular form of machine shown, as the same may be varied as to details of its construction without in any way departing from the spi'rit of the invention.

Having thus described my invention, what I claim to benew, and desire to secure by Letters Patent, is

1. An apparatus for treating the soil, comprising a truck-frame, stubshafts fixed to the front face of the cross-beam at the forward end of the truck, wheels journaled on said shafts, a disk-carrying rack, hinge straps secured to the forward end thereof and engaging recessed portions of the front cross-beam of said truck, a shaft journaled in saidrack, circular disks fixed to said shaft, carried by said rack, beams fixed at their forward ends to the forward cross-piece of the rack, strips, secured to the under faces of said beams and designed to bear frictionally against the diskcarrying shaft, and a handle connecting the rear ends of said beams, as set forth.

2. An apparatus for treating the soil, comprising a truck-frame, stub-shafts fixed to the front face of the cross-beam at the forward end of the truck, wheels journaled on said shafts, a disk-carrying rack, hinge-straps secured to the forward end thereof and adapted to turn in recessed portions in the front crossbeam of said truck, a shaft journaled in said rack, circular disks fixed to said rack-carrying shaft, beams fixed, at their forward ends, to'the forward cross-piece of the rack, strips secured to the under faces of said beams and designed to bear against said disk-carrying shaft, the rear portion of said truck havinga raised portion beyond the rear ends of said strips, and a handle connecting the rear ends of said beams, as set forth.

In testimony whereof I hereunto ailix my signature in presence of two witnesses.

GEORGE H. ADAMS.
